Mold-Masters to show controller, new nozzle
Mold-Masters Ltd. will feature a new hot runner temperature controller and a new nozzle at the K 2001 show in October.
Temp-Master Multi-Zone TMMZ will be available in two initial models, one for up to 24 zones, the other for up to 84 zones. Each zone will be capable of a 16 ampere load, 60 percent greater than conventional 10 ampere zones in competing products. The design includes a compact footprint, a single-board design for easy maintenance and redundant safety systems to protect the heater circuits.
The Georgetown, Ontario, firm also will unveil a new one-piece cartridge heater nozzle that turns the melt channel into a heater. Nozzle diameter is less than 10 millimeters with minimal gate vestige. Mold-Masters claims it is well suited for small, cosmetic parts and for high cavitation tooling. The heater, tip and melt channel are integral for better thermal control and less maintenance.

Motoman updates 2 types of software
Robot maker Motoman Inc. has introduced Version 3.0 of its MotoCal software, now allowing technicians to re-calibrate an entire robotic work cell, including robot arms, end-of-arm tooling and fixtures.
MotoCal can identify subtle ``as-built'' differences in robots and then filters programs to greatly reduce the need for manual touch-up work as programs are downloaded, moved or adjusted when robots are repaired.
The company in Dayton, Ohio, also issued Version 6.2 of its personal computer-based simulation software, renaming the ROTSY product MotoSim. The software reduces programming time, as the user can see a virtual robot system with clear, three-dimensional graphics. The robot can be viewed from any angle. The software calculates cycle times and displays velocities for each robot axis.

S.W. Filtration shows new cartridge filter
S.W. Filtration Inc., which makes large-area type filter systems used in compounding, polymer production and other forms of extrusion, has introduced an affordable cartridge filter for fibers operations: the Moduloscreen.
The filter handles up to 4,400 pounds of material an hour. The compact system lets processors adjust the flux rate, filter life and residence time, depending on the throughput, micron rating and product. It also can filter several polymers from different extruders simultaneously. Hydraulic ram-type valves allow continuous extrusion while other filter elements are being replaced or cleaned.
A modular design allows up to three single-filter-element housings to be added to a common base.
S.W. Filtration, based in Anderson, S.C., is the U.S. headquarters of Southwest Screens & Filters S.A. of Sprimont, Belgium.
S.W. Filtration also said it is working with JLS International Inc., a firm in Charlotte, N.C., to expand its filter business globally.
The firm makes its products in Belgium and Jakarta, Indonesia.

Thermacore expands heat exchangers line
Thermacore International Inc. has expanded its line of heat exchangers with a new high-performance model, dubbed Hxi-1500+.
The Lancaster, Pa., firm developed the unit for custom applications with heat dissipation requirements of 1,500 watts and above.
The Hxi series utilizes Thermocore's patent-pending double-sided impingement cooling technology, which provides up to 50 percent more heat transfer than similarly sized competitive units.
Thermocore is a subsidiary of Modine Manufacturing Co.

Comet Automation creates disc division
Comet Automation Systems Inc., an auxiliary equipment manufacturer in Dayton, Ohio, has created an Optical Disc Division to target that new market.
Comet is partnering with Lanco of Hanau, Germany, which makes dryers for the compact disc industry. The new Comet/Lanco modular dryers are designed for audio-CD, CD-ROM, CD-R and CD-MO formats, as well as the digital-versatile-disc format.
Comet named Sam Rajkovich sales manager for the division.
Also, Comet introduced the CE-1000 weigh color feeder. The screw-metering unit is designed for precise metering of powders and color concentrates into the feed throat of a machine.
The CE-1000 comes in two versions. The SM-D has a step motor for injection presses. The DC-D uses a direct-current drive motor for extruders. For changing colors or cleaning, the entire module is removed from the machine.

United Air Specialties touts Kleentek ability
Cincinnati-based United Air Specialties Inc. said its Kleentek electrostatic oil-cleaning machines remove insoluble contaminants, including tars and varnishes, from hydraulic oil systems in injection molding machines.
Those sticky substances adhere to surfaces, causing loss variations in performance, the need for constant valve adjustment and reduced machine performance. Kleentek reduces the need for oil changes.
Disposable filters made of cellulose fiber can hold as much as 10 pounds of material before they need changing, good for between 2,000 and 10,000 hours of use.

Raytek introduces thermoforming device
Raytek Corp., which makes noncontact temperature controllers, introduced a device for thermoforming dubbed the TF100 System.
The TF100 monitors the temperature distribution of the sheet, reducing setup time and scrap and improving quality. It measures temperature of a sheet as it leaves the oven, while being transported to the forming section.
The data is transmitted to a personal computer.
Raytek of Santa Cruz, Calif., said the system can be used within minutes after the process imager is installed.
The system subdivides the data into any number of rectangular zones, corresponding to zones in the oven.

Central processing unit controls pipe coilers
Mecasoft sarl of Soultz, France, said its pipe coilers now can be controlled by a central processing unit, reducing the main control cabinet on each coiling machine.
The coiler adapts itself to changes in the speed of the extruder. For high-production lines, Mecasoft also offers a device that automatically inserts twine during the strapping operation. A pneumatically powered strapping head is mounted as standard on all of the firm's coilers.
